Detailed Description Of The Invention
The inventor is surprised to find, a kind of important component of eye vitreous, and hyaluronic acid can be regulated and pass through adenopathy The genetically modified expression of poisonous carrier transfered cell and the infectiousness of wild-type adenovirus. The inventor is surprised to find, The hyaluronic acid of HMW itself or as Vitrea a kind of composition pass through adenopathy with external can the enhancing in vivo Poisonous carrier is from the functional genetically modified expression of eye external environment transfered cell. The enhancing of this expression does not rely on adenopathy Poisonous carrier adheres to and enters cell.
More wondrous and meaningfully, the inventor find low-molecular-weight hyaluronic acid can suppress adenovirus infection and The transduction of adenovirus vector. The most meaningfully, low-molecular-weight hyaluronic acid, or by enzymatic reaction or other Process the low-molecular-weight hyaluronic acid through modifying or degrading, all can be used to treat the adenovirus infection disease. Therefore, The hyaluronic acid of low-molecular-weight or modification or vitreum can be used as the preventative or therapeutic combination for the treatment of adenovirus infection Thing.
Inhibitory action refer to a kind of preparation partially or completely stop, limit, slow down, reduce, postpone, reduce, suppress, The compacting or disturb certain biological process, with any degree, partially or completely. Therefore, inhibitor be can the part or Stop fully, limit, slow down, reduce, postpone, retrain, reduce, suppress, suppress or disturb certain biology mistake Journey, biochemical reaction for example, virus or Growth of Cells or other physiology courses include but not limited to infect or disease Sick process, disease or Life Cycles process, the preparation of organ dysfunction or performance etc.
The inventor finds that also hyaluronic acid is by activating activity in a series of cells with the CD44 effect, and CD44 is A member of common adhesion molecule family on many cell types. Therefore, the energy specific binding is in hyaluronic acid The antibody that the hyaluronic acid of CD44 activates is also blocked in the binding function territory, suppressed simultaneously vitreum-enhancing and baseline Adenovirus mediated transgene expression. Can express the Jurkat cell of CD44 through engineering improvement, but not be known Do not express the wild type Jurkat cell of CD44 or any other hyaluronic acid bind receptor, may be presented at existence Can suppress the enhancing of the transgene expression of adenovirus vector conveying when vitreum or high molecular weight hyaluronic acid. Phorbol Ester has strengthened the effect that vitreum produces greatly. Report in the past shows that PMA can cause the oligomerization of CD44 with sharp Live. Can cultivate to produce with lyases the low-molecular-weight hyaluronic acid of (or with hyaluronic acid out-of-date or degraded), Not only can not strengthen adenovirus mediated transgene expression, and amazing and suppressed unexpectedly the baseline gland The transgene expression of viral vectors mediation.
Above-mentioned enhancement effect does not rely on used promoter or transgenosis, but is special to adenovirus vector, namely Make them utilize different associativities or internalization acceptor. The time course prompting hyaluronic acid of this effect is for adenopathy The enhancing that the poison gene transfer is expressed occurs in after viral combination and the internalization.
Report in the past proved HMW hyaluronic acid can in conjunction with and activate the CD44 signal transduction, but low branch Son amount hyaluronic acid can in conjunction with but do not activate identical mechanism. Therefore low-molecular-weight hyaluronic acid has played the CD44 function and has pressed down The effect of preparation. High molecular weight hyaluronic acid has strengthened adenovirus mediated genetically modified expression, yet low-molecular-weight Hyaluronidase has suppressed the baseline adenoviral transduction. The glucuronic acid of the basic unit of formation hyaluronic acid-N-acetyl Portugal Grapes glucosamine disaccharide can activate CD44 but only when endocellular injection. CD44 has the cell function of many complexity, comprises Play the function of cell traffic albumen, control cytoskeletal structure and motility, and by control microtubule and the moving egg of flesh The transhipment of intracellular protein is regulated in white assembling. Anti-by the CD44 modulability cascade that low-molecular-weight G-is protein mediated Should have influence on many these functions.
1. adenovirus
Adenovirus comprises linear dsdna, and genomic size is 30-35kb (Reddy etc., 1998; Morrison Deng, 1997; Chillon etc., 1999). The human adenovirus that has the serotype more than 50 kinds, and 80 kinds with On correlation form, they can be divided into 6 families (Wadell etc., 1980) according to immunity, molecule and profile. On the physics, adenovirus is a kind of medium sized icosahedron viruses, contains a double-stranded linear DNA genome, For example Adenovirus Type 5 has 35,935 base-pairs (Chroboczek etc., 1992). Adenovirus require enters the host Cell and viral genome is transferred to nucleus could infection cell and replication-competent virus.
The notable feature of adenoviral gene group is an early region (E1, E2, E3 and E4 gene), a mesozone Territory (pIX. gene, Iva2 gene), a zone in late period (L1, L2, L3, L4 and L5 gene), a main evening Phase promoter (MLP), inversion-end-duplicate block (ITRs) and psi sequence (Zheng etc., 1999; Robbins Deng, 1998; Graham and Prevec, 1995). Described early gene E1, E2, E3 and E4 after infection from disease Poison is expressed, the polypeptide of its coding can regulate viral gene expression, cytogene expression, virus replication and press down Apoptosis processed. Further during virus infections, MLP is activated, and this has caused the expression of (L) gene in late period, The adenovirus capsidization of the polypeptide of coding is required. Described mesozone encoding adenovirus capsid component. Adenovirus is inverted Terminal duplicate block (ITRs; 100-200bp length), be cis element, play a part replication initiation, be virus Dna replication dna institute is essential. Described psi sequence is that adenoviral gene group packing is necessary.
The mechanism that adenovirus, particularly adenovirus serum 2 types and 5 types infect has been subjected to broad research. Identify A kind of host cell surface protein called after CAR (Ke's Sa Room adenovirus receptor) is the main combination of these adenovirus Acceptor. The cell endogenous function of CAR is not also illustrated. Interaction between fiber ball-joint and the CAR is enough to make gland Virus is bonded to cell surface. Yet, subsequently the penton base of adenovirus and other cell cortex proteins, αvInteraction between the member of integrin family is that effectively internalization is necessary for virus. Adenovirus (component) Dissociate and during internalization, begin; Celloglobulin is stayed cell surface and is incorporated into CAR, all the other components of adenovirus along with Virion is transported by cytoplasm and is in a step-wise fashion dissociated at formation hole, nuclear membrane place complex. Viral DNA is discharged Enter nuclear by nuclear membrane, viral DNA copies in nuclear, expresses virus protein, is assembled into new virion. Specific step in the adenovirus infection mechanism can be used as the potential target of regulating virus infections and gene expression.
2. the improved adenovirus of genetic engineering and adenovirus vector
In specific embodiments, consider to carry the expression construction with adenovirus expression carrier. " gland virus expression carries Body " or " adenovirus vector " comprise that those are enough to (a) and support the packing of described construction and (b) final express The construction of gland-containing virus sequence has been cloned in tissue or the cell-specific structure. Therefore, adenovirus vector The carrier that can comprise the engineering distribution distribution transformation of any gland-containing virus sequence.
Adenovirus expression carrier of the present invention comprises the genetic engineering modified form of adenovirus. The character of adenovirus vector is not Think successful implementation key of the present invention. Adenovirus can be one of serotype known to any and/or subgroup A-F. In order to obtain to can be used for a kind of viral vectors of gland among the present invention, the Adenovirus Type 5 of subgroup C is preferred parent material. This is because Adenovirus Type 5 is a kind of adenovirus hominis, knows about its large number of biological chemistry and hereditary information, And it has been used in history great majority and has adopted in the structure of adenovirus as carrier.
The advantage that adenoviral gene shifts has; Can infect far-ranging cell type (comprising non-fissility cell), Medium sized genome, simple to operate, high infectious, and they can with high titre propagation (Wilson, 1996). In addition, the adenovirus infection of host cell can not cause chromosomal integration, because adenovirus DH can swim Copy from mode, not the latent gene toxicity relevant with other viral vectors. Adenovirus structurally also is stable (Marienfeld etc., 1999), and after a large amount of amplifications, do not measuring genomic rearrangement (Parks etc., 1997; Bett etc., 1993).
The growth of adenovirus and operation are that this art person knows, and show that host in the wide external and body is arranged Scope (United States Patent (USP) 5,670,488; United States Patent (USP) 5,932,210; United States Patent (USP) 5,824,544). This group virus Can be high titre obtain for example 109-10 11Plaque forming unit/ml, they have hyperinfection. Adenovirus Life cycle does not need to be integrated in the host cell gene group. The alien gene that adenovirus vector is carried is episome, Therefore be low genotoxicity for host cell.
Although adenovirus vector is compared with other carrier systems several unique advantages are provided, their application is frequent Be subjected to the immunogenicity of carrier, the size constraint that recombination inserts, the low and transgene expression water of levels of replication Flat low restriction. A major concern point of using adenoviral vectors be during carrier produces in package cell line or During the gene therapy individuality, whether produced replication activity virus. The generation of replication activity virus may be to patient Cause the serious threat of the unexpected virus infections that arrives and pathological examination. Armentano etc. have described the replication defective venereal disease Potential feasibility (the United States Patent (USP) that can eliminate the replication activity adenovirus and produce is unintentionally claimed in the preparation of poisonous carrier 5,824, No. 544). The method of this kind replication defective adenoviral comprises deletion E1 zone and replacement protein IX gene, Wherein said carrier can the expressing heterologous mammalian genes.
The common method that a kind of generation can be used as transgenosis carrier adenovirus is deletion E1 gene (E1), and this relates to The inducing of E2, E3 and E4 promoter (Graham and Prevec, 1995). Then the therapeutic gene restructuring is inserted and get For the E1 gene, wherein the expression of therapeutic genes is driven by E1 promoter or allogeneic promoter. Then " auxiliary Hand " propagation E1-replication defective virus in the clone, this auxiliary cell line can provide trans E1 polypeptide (people's embryo for example Tire kidney cell line 293). Perhaps, can delete the E3 zone, part E4 zone or both can be in eukaryotics Heterologous nucleic acid sequence under the promoter control of operation is inserted in the adenoviral gene group, and (U.S. is special to be used for gene delivery Sharp the 5th, 670, No. 488; United States Patent (USP) the 5th, 932, No. 210).
Certainly, in specific embodiments of the present invention, consideration can be with low-molecular-weight or modified hyaluronic acid or glass The glass body is used for treating the replication activity adenovirus of this careless lower generation. As mentioned above, consider that the present invention should adopt Carrier be replication defective. Yet, consider that also the method that contains the replication activity adenovirus vector may lead Cause so-called amplification. Therefore, consider that specific embodiment is, can by use low-molecular-weight or modified thoroughly Phaneroplasm acid or vitreum are regulated amplification degree and the speed of replication activity viral vectors.
(AdV5/F35, for example), they can flow to transgenosis to have produced a class mosaic adenovirus vector Hematopoietic progenitor. Very effective when the AdV5/F35 carrier is transitted to original progenitor with transgenosis (Yotnda etc., 2001). These carriers also can infect the hoechst feminine gender ' secondary group ' of bone marrow cell. Carried by these carriers Immunomodulatory gene can transduce and express about more than 5 days with certain level. In the present invention one preferred enforcement side In the case, with hyaluronic acid process transgenosis by this chimeric adenoviral vectors importing (such as but not limited to AdV5/F35), can fully strengthen genetically modified expression.
3. carry out gene therapy with adenovirus and adenovirus relevant carriers
In certain embodiments, the inventor considers to strengthen with hyaluronic acid or vitreum and related compound and leads Enter the genetically modified expression in the cell, thereby reach gene therapy purpose.
Gene therapy generally includes the transgenosis transfered cell, genetically modified expression of results be alleviate or treated disease or Genetic disease. Included transgenosis can be those coded proteins, structural or ribozyme s, suppress to produce Thing is antisense RNA or DNA for example, or other any gene outcomes. Expression be this gene outcome production process or This gene outcome produces the effect that takes place. Therefore, strengthen to express comprise produce more certain transgene product or Promote this product in the cell that limits, tissue, organ or the effect in the fuselage state. Defeated by adenovirus vector The cell transduction that send transgenosis to comprise to be called as. As used herein, transduction is defined as by adenovirus or relevant carriers With transgenosis or transgenosis construct transfered cell.
Many experiments, new invention, preclinical phase research and clinical testing are at present adopts adenovirus defeated as gene Send the conceptual phase of carrier. For example, developing take the adenoviral gene conveying as the basis gene therapy be used for the treatment of Hepatopathy (Han etc., 1999), mental illness (Lesch, 1999), sacred disease (Smith, 998; Hermens and Verhaagen, 1998), coronary artery disease (Feldman etc., 1996), muscle disease (Petrof, 1998), with And various cancers such as colorectal cancer (Dorai etc., 1999), carcinoma of urinary bladder (Irie etc., 1999), prostate cancer (Mincheff etc., 2000), head and neck cancer (Blackwell etc., 1999), breast cancer (Stewart etc., 1999), lung Cancer (Batra etc., 1999) and oophoroma (Vanderkwaak etc., 1999). In specific embodiments of the present invention, Adopt high molecular weight hyaluronic acid or vitreum to improve the genetically modified expression that adenovirus vector is carried.
Therefore, target of the present invention can by raising be included in the therapeutic genes in the gene delivery system expression and Realize that this induction system for example is the recombinant adenoviral vector induction system, this system of preparation can make by transducer cell The contact expression facilitator, for example high molecular weight hyaluronic acid or vitreum, and cause the enhancing table of this therapeutic genes Reach.
Describedly can be present in the cell culture or in the body by transducer cell.In vivo, such as considered in the present invention, cell can be arranged in any tissue or the organ of relevant body.Tissue can comprise host cell or cell to be changeed or the cell that contacts with nucleic acid delivering composition and/or other preparations.Described tissue can be the part of body or obtain from its separation.In certain embodiments, tissue and its composition cell can include but not limited to, blood (hematopoietic cell (for example artificial blood progenitor, human hematopoietic stem cell, CD34 for example +Cell, CD4 +Cell), lymphocyte and other blood pedigree cells), bone marrow, brain, stem cell, blood vessel, liver, lung, bone, breast, cartilage, cervix uteri, colon, cornea, embryo, endometrium, endothelium, epithelium, esophagus, fascia, fibroblast, folliculus, ganglionic cell, neurogliocyte, goblet cell, kidney, lymph node, muscle, neuron, ovary, pancreas, peripheral blood vessel, prostate, skin, small intestinal, spleen, stomach, testis.
In certain embodiments, described host cell or tissue pocket are contained at least one body.In certain embodiments, but this body people, Primate or mice.In other embodiments, this body can be any adenovirus and correlated virus or adenovirus vector eukaryote or eukaryotic cell that infect or transduction of being subject to.The person skilled in art can further understand should cultivate above-mentioned host cell under what conditions, thereby preserves them and make their divisions form generation.
Developed the strategies in gene therapy that is used for treatment of cancer.Developed according to the diverse ways of gene rotating method and treated tumor.The method of having developed is corrected the special damage of determined gene loci, and this infringement can make tumor transform and development (Spandidos etc., 1990; Banerjee etc., 1992).Can the employing technology make the overexpression of dominance oncogene to suppress transformed gene or gene outcome.The forfeiture of tumor suppressor gene function can the employing method recovers the function of wild type tumor suppressor gene.Except these realize the method for sudden change compensation, developed genetic technique and come specificity and selectivity to eradicate tumor cell.These molecular chemistry Therapeutic Method depend on specific expressed (Abe etc., 1993) of toxin gene in the tumor cell.At last, gene transfer method has been used to realize the antineoplastic immune inoculation.These heritability immunostimulant methods have adopted hereditary regulation technology, improve the immunity identification to tumor.As a result, developed the gene therapy that multiple distinct methods is realized cancer, all methods all adopt the adenovirus vector transducer cell.
Hurwitz etc. (1999) have described a kind of adenovirus vector that contains simple skin ulcer rash (virus) thymidine kinase gene, when external transduction goes into to use the treatment of prodrug gancyclovir in the Y79Rb human retinoblastoma cell with it, can effectively promote killing and wounding to those retinoblastoma cells.A kind of retinoblastoma mouse model of making by intravitreal injection Y79Rb cell also responds to transduction and treatment.Therefore, gene therapy can effectively reduce the tumor load in the human retinoblastoma mouse model.Obviously, the fragmentation effect that can further increase this therapy is expressed in the genetically modified enhancing of adenovirus vector conveying.Specifically, environment is in the vitreous body within the eye, and it is favourable that the expression of adenovirus vector strengthens.More generally, to be presented in the animal model treatment kinds of tumors be effective to AdV-TK/ gancyclovir suicide gene therapy.See for example Eastham etc., 1996 (prostate); Chen etc., 1994 (brains); Chen etc., 1995 (livers); O ' Malley etc., 1995 and Goebel etc., 1996 (necks); Behbakht etc., 1996 and Rosenfeld etc., 1996 (ovaries); Esandi etc., 1997 (mesotheliomas).Specific embodiments of the present invention comprises (effect) that adopts hyaluronic acid to strengthen or promote the gene therapy of AdV-TK/ gancyclovir.
The concrete transgenic that adenovirus vector is carried comprises that without limits those can be used for various treatments and research purpose transgenic, and reporter gene and reporter gene system and being used for follows the tracks of the construction of transgene expression and adenovirus and adenovirus vector transduction effectiveness.Therefore, as an example, be the possible gene type that possible strengthen expression below with the compositions and methods of the invention; Development gene (adhesion molecule for example, the cyclin inhibitors of kinases, the Wnt family member, the Pax family member, Winged spiral family member, the Hox family member, cytokine/lymphokine and their receptor, growth or differentiation factor and their receptor, neurotransmitter and their receptor), oncogene (ABLI for example, BLC1, BCL6, CBFA1, CBL, CSFIR, ERBA, ERBB, EBRB2, ETS1, ETV6, FGR, FOX, FYN, HCR, HRAS, JUN, KRAS, LCK, LYN, MDM2, MLL, MYB, MYC, MYCL1, MYCN, NRAS, PIM1, PML, RET, SRC, TAL1, TCL3 and YES), tumor suppressor gene (APC for example, BRCA1, BRCA2, MADH4, MCC, NF1, NF2, RB1, TP53 and W1), (for example ACP desaturase and hydroxylation are quick for enzyme, the ADP-glucose pyrophosphorylase, the ATP enzyme, alcoholdehydrogenase, amylase, amyloglucosidase, catalase, cellulase, cyclo-oxygenase, decarboxylase, dextromase, esterase, DNA and RNA polymerase, hyaluronic acid synthetase, tilactase, glucanase, glucoseoxidase, the 6TP enzyme, unwindase, hemicellulase, hyaluronidase, intergrase, invertase, isomerase, kinases, Lactose enzyme, lipase, lipoxygenase, lyases, lysozyme, pectinesterase, peroxidase, phosphatase, phospholipase, phosphorylase, polygalacturonase, protease and peptidase, amylopectase, recombinase, reverse transcription, topoisomerase, xylanase), and reporter gene (the multiple color variations body of green fluorescent protein matter and it for example, luciferase, the CAT reporting system, beta galactosidase or the like).
The function of tumor suppressor gene is to suppress exhausted cell proliferation.The deactivation of these genes has destroyed their inhibition activity, has caused immoderate propagation.Tumor inhibitor p53, p16 and C-CAM are described below.
Think that at present p53 is a tumor suppressor gene.Having found that high-caliber p53 mutant is present in manyly comprises in the S40 cell transformed through chemical carcinogenesis, ultrasonic emission and multiple virus.The p53 gene usually is the target of sudden change deactivation in various people's tumor, and has proved in the common human cancer gene of the most frequent sudden change.It is undergone mutation in other tumors above (Hollstein etc., 1991) among 50% the people NSCLC and wide model.
A kind of 393-aminoacid of p53 gene code phosphoprotein, energy and host protein, for example big-T antigen and E1b form complex.This protein sees in normal structure and the cell, but compares with transformant or tumor tissues, and concentration is extremely low.Interesting is that wild type-p53 it seems that be important in regulating cell growth and division.The overexpression that has shown wild type-p53 in some cases has anti proliferative in human tumor cell line.Therefore, p53 may play a part the negative regulator (Weinberg, 1991) of cell growth, may directly suppress the gene that sexual cell growth out of control or indirect activation suppress this growth.Therefore, the shortage of wild type-p53 gene or inactivation may cause transforming.Yet some studies show that the existence of p53 mutant may be that this gene transformation potential is expressed necessary fully.
Wild type-p53 is considered to a kind of important growth regulator in many cell types.The sudden change of missense is common in the p53 gene, is that the oncogene conversion capability is necessary.The individual gene change that is caused by point mutation can produce carcinogenecity p53.Yet, do not resemble other oncogene, according to known to the p53 point mutation occur at least in 30 different codons, often produce dominant allele and the change of cell phenotype take place, but can not be reduced to homozygosity.In addition, it seems that many these dominance negative alleles can be tolerated by body and go down to posterity in kind of system.Various mutant alleles seem scope and show the dominance negative allele (Weinberg, 1991) outside intensive from the dysfunction of minimum.
The DNA that Casey and colleagues report encoding wild type-p53 is transfected among two kinds of human breast cancer cell lines, has recovered this cytostatic control (Casey etc., 1991).Proved that also wild type rather than mutant p53 transfection enter the human lung cancer cell line and have similar action (Takahasi etc., 1992).It seems that p53 is better than mutant gene, when with the mutant gene transfectional cell, will select it to resist propagation.The normal expression of transfection p53 can not influence the growth that contains endogenous p53 cell.Therefore, such construction can be absorbed by normal cell and be free from side effects.Therefore, propose to reduce the quantity of malignant cell or reduce their growth rate with wild type p53 treatment p53 associated cancer.
The main transition in eukaryotic cell cycle is subjected to the triggering of the kinases or the CDK of dependent cells cycle regulating protein.A kind of CDK, cyclin dependant kinase 4 (CDK4) is regulated its development by G1.Active receptor 1 activity subunit, D-type cyclin and the inhibition subunit p16 of CDK4 INK4Control.P16 INK4Through biochemical characteristic be accredited as a kind of can specificity in conjunction with and suppress the protein of CDK4 so the phosphorylation of scalable Rb (Serrano etc., 1993; Serrano etc., 1995).Because p16 INK4Albumen is CDK4 inhibitor (Serrano, 1993), and the disappearance of this gene can increase the activity of CDK4, causes the proteinic high phosphorylation of Rb.Know that also P16 can regulate the function of CDK6.
P16 INK4Belong to the CDK-repressible protein matter that a class is described recently, also comprise p15 INK4B, p21 WAF1And p27 KIP1P16 INK4Gene map is positioned at 9p21, a chromosomal region that often lacks in many tumor types.P16 INK4The homozygosity disappearance and the sudden change of gene are common in human tumor cell line.This true prompting p16 INK4Gene is a kind of tumor suppressor gene.Yet this explanation has been subjected to challenge, because observe p16 INK4Gene is not cultivated change frequency ratio much lower (Caldas etc., 1994 in cultured cells system in the tumor in former generation; Cheng etc., 1994; Hussussian etc., 1994; Kamb etc., 1994; Mori etc., 1994; Okamoto, 1994; Nobori etc., 1995; Orlow etc., 1994; Arap etc., 1995).Yet, in many former generations tumor, be complete though showed the p16 gene afterwards, exist other mechanism to stop p16 protein in the great majority of some tumor types, to be expressed.The hyper-methylation of P16 promoter is (Merlo etc., 1995 in these mechanism; Herman, 1995; Gonzalez-Zulueta, 1995).Recover wild type p16 by the plasmid expression vector transfection INK4The function colony that can reduce some cancerous cell lines form (Okamoto, 1994; Arap, 1995).Carry p16 can suppress the propagation of some cancerous cell lines and the growth of reduction people tumor xenogeneic graft with adenovirus vector.
In fact C-CAM has expression (0din and Obrink, 1987) in all epithelial cells.C-CAM, apparent molecular weight 105kD, by with energy in and the specific antibody of cell agglutination reaction (Obrink, 1991) initial separation from the cytoplasmic membrane of rats'liver cell.Recent studies show that structurally, C-CAM belongs to immunoglobulin (Ig) superfamily, its sequence and carcinoembryonic antigen (CEA) height homology (Lin and Guidotti, 1989).Adopt baculovirus expression system (Cheung etc., 1993) to show that the Ig zone of C-CAM is that cell adhesion activity is vital.
Known cell adhesion molecule, or CAM ' s participates in the complex network of intermolecular interaction, and this network adjustment organ is sent out clothing and cell differentiation (Edelman, 1985).Nearest data show that the unconventionality expression of CAM ' s may participate in the generating process of several tumors; For example, the reduction of the E-cadherin expression of mainly expressing in epithelial cell is with development relevant (Edelman and Crossin, 1991 of several tumors; Frixen etc., 1991; Bussemakers etc., 1992; Matsura etc., 1992; Umbas etc., 1992).Equally, (Giancotti and Ruoslahti, 1990) prove that improving α 5 β 1 by gene transfer in the body integrates the tumor generation that plain expression can reduce Chinese hamster ovary cell.Proved that now C-CAM can suppress external and intravital tumor growth.
Relevant (MDA) gene of melanoma differentiation is relevant with differentiation with the human melanoma cell growth, or directly influences their (Su etc., 1998).Recently the tumor promotion that resist-causes that studies have shown that the MDA family member is not limited to melanoma.The expression inhibiting of MDA-7 the growth of external glioblastoma, osteosarcoma, colorectal cancer, breast carcinoma, cervical cancer and nasopharyngeal carcinoma (Jiang etc., 1996).The expression of MDA-7 transfers the effect of dying to suppress the growth of vitro human breast cancer cell and the growth (Su etc., 1998) of the interior xenograft models of body by inducing.
Other adoptable tumor inhibitors of the present invention comprise BRCA1, BRCA2, zac1, p73, MMAC-1, ATM, HIC-1, DPC-4, FHIT, NF2, APC, DDC, PTEN, ING1, NOEY1, NOEY2, PML, OVCA1, MADR2, WT1,53BP2 and IRF-1.

4. hyaluronic acid
Hyaluronic acid has numerous characteristics, and they may be favourable in other therapeutic treatments and bioprocess.In fact, hyaluronidase is general in treatment and other application of disease, infection.The scope of these application is from simple lubricated, to the conveying of medicine, to the treatment of retrovirus infection.For example see United States Patent (USP) the 6th, 194, No. 392, the 6th, 218, No. 373, the 6th, 271, No. 216, the 4th, 840, No. 941.See Hoekstra equally, (1999) and Lee and Spicer, (2000).
Hyaluronic acid, hyaluronan or hyaluronic acid are a kind of natural polysaccharides (glycosaminoglycan) that exists, and are formed by the repetitive that β 1-3 glycosidic bond is connected with N-acetyl-glucamine by glucuronic acid.These unit are connected to form by β 1-4 glycosidic bond does not have ramose strand.This chain negative charge when the carboxyl ionization of glucuronic acid.It occurs in and produces hyaluronate sodium under the physiology pH value.Hyaluronic acid is good at maintenance moisture very much.
Hyaluronic molecular weight is can be different with concentration in the eye vitreous, depends on the body species that it exists, hyaluronic position in the eyes, and the method for analyzing molecules amount.Therefore, hyaluronic molecular weight can be from 50, and 000Da is above different, and it can form full-bodied solution.It is one of the abundantest chemical compound of human body, is generally used in the extracellular matrix to support and the protection cell.It is present in all body fluid, but at the vitreous humor of eyes, many especially in synovia and the umbilical cord.Hyaluronic acid is a hydrophilic and very lubricated.
The Merck index has determined that hyaluronic molecular weight is 50,000 to 8 * 10 6Within dalton (Da) scope, depend on source, preparation method and assay method.The Merck publication is lectured hyaluronic acid and is a kind of adminicle of external coat.United States Patent (USP) the 4th, 801, having disclosed the hyaluronan molecule amount that intraarticular gives for No. 619 approximately is 3 * 10 6Da or higher.
Hyaluronic acid is separable in the culture of vertebrates tissue (for example people's umbilical cord, rooster comb) or generation bacterial strain.Various other hyaluronic acids of level can be from commercial acquisition.For example see the hyaluronic acid catalogue entry of Sigma.A kind of high-purity, non-inflammatory formal description be in United States Patent (USP) the 4th, 141, No. 973.A kind of commercial product, Healon TMCan be from Pharmacia AB (Uppsala, Sweden) acquisition.Hyaluronic acid in this preparation it is said that molecular weight surpasses 750, and (can further surpass 1,200,000Da), and proposition can be applicable to the treatment of various joints situation to 000Da.
There is many hyaluronic acids manufacturer in the whole world.These comprise Anika (Woburn, MA), Biomatrix Inc. (Ridgefield, NJ), Bio-Technology General Corp. (IselinNJ), and Fidia AdvancedBiopolymers (Brindisi, Italy), Genzyme Corp. (FraminghamMA), Kibun Food ChemifaCo. (Tokyo, Japan), Lifecore Biomedical (Chaska, MN) and Seikagaku Corp. (Tokyo, Japan).
The hyaluronic low-molecular-weight precursor of high molecular polymerization natural synthetic thought to be produced by hyalocyte.High-molecular weight hyaluronic acid is formed at ECS, in most cases is the effect by hyaluronic acid synthetase.Exist multiple hyaluronic acid synthetase, can be used for producing hyaluronic acid (Spicer and Mcdonald, 1998) from the low-molecular-weight precursor to the high molecular form.The activity of hyaluronic acid synthetase can be easy to measure (Spicer, 2001).
High molecular weight hyaluronic acid can be handled with enzyme, causes reclaiming its derivant or low-molecular-weight form by hyaluronidase or lyases (EC4.2.2.1).See United States Patent (USP) the 6th, 258, No. 791.Hyaluronidase summary see Kreil (Protein Sci, 1995,4:1666-1669).Hyaluronidase can be from mammal, reptile or hymenopteran hyaluronic acid polysaccharide hydrolytic enzyme, hyaluronic acid polysaccharide hydrolytic enzyme from the Hirudo salivary gland, or from antibacterial, particularly streptococcus, streptococcus pneumoniae and clostruidium hyaluronate lyase.Hyaluronidase extensively obtains from commercial supplier.For example see the hyaluronidase clauses and subclauses (2002) among the Sigma-Aldrich.
5. regulate adenovirus mediated gene expression and the application in adenovirus infection with hyaluronic acid or vitreous body
The inventor has obtained discovery wondrous and beyond expectation, the derivant of high molecular weight hyaluronic acid is a low-molecular-weight hyaluronic acid, " out of date " high molecular weight hyaluronic acid, high molecular weight hyaluronic acid with lyases or hyaluronidase processing, or, can significantly suppress the cell transduction of adenovirus and adenovirus vector through such vitreous body of handling.The unexpected characteristic of these compositionss makes it possible to treat adenovirus infection, the transduction of the infection of replication activity adenovirus vector and adjusting adenovirus vector.
Low-molecular-weight hyaluronic acid is considered among positive the present invention, comprises the product of the high molecular weight hyaluronic acid of contacted energy degraded macromolecular amount form or vitreous body environment.This degraded can be handled or realizes by the hyaluronic acid or the sufficiently long time of vitreous body ingress of air that make the high molecular form by enzyme, perhaps selects than clinical practice permission more aged hyaluronic acid of date or vitreous body.This catabolite can be discerned by analyze complete, unmodified or the fresh hyaluronic acid and the comparison of catabolite with gel electrophoresis method.
Specifically, a kind of limiting examples of this comparison comprises the electrophoresis that carries out associated sample, 0.5% agarose (TAE sees Sambrook 2001) of joining by 1X Tris acetic acid edta buffer liquid.Sample can be added in the hole of agarose gel, join (2M sucrose in the 8x sample loading buffer of 1 volume with 7 volume sample; 1.5M NaCl) and be exposed to the 80-100 volt 4-6 hour.Behind the electrophoresis, the 0.005%StainsAll that joins with 50% ethanol in the dark TM(4,5,4 ', 5 '-hexichol-3,3 '-diethyl-9-methyl-thiono cyanogen bromide; 3,3'-diethyl-9-methyl-4,5,4 ', 5 '-hexichol thiono cyanogen; 1-ethyl-2-[3-(3-ethylnaphthalene [1,2-d] thiazoline-2-alkenylene)-2-first acrylic] naphthalene [1,2-d] thiazole  bromide, Sigma-Adrich Co. Inc.) handled 12 hours or spends the night.Then water cleans gel and removes not combination dye.Can manifest hyaluronic acid in 30 minutes by the gel exposure that will handle like this.As what arrive known to these those skilled in the art, the molecular weight of other more transparent matter acid enzyme samples and the method for other characteristics are that these those skilled in the art know, can be used in the context of the present invention, can effectively suppress the sample of adenovirus infection or adenovirus vector-mediated transgene expression to identify those.
Specifically, the inventor provides the method for screening suitable hyaluronidase sample here, as the inhibitor or the reinforcing agent of adenovirus infection or adenovirus mediated transgene expression.Therefore, can screen high molecular weight hyaluronic acid, or contact or high molecular weight hyaluronic acid of handling thereby the sample that has produced low-molecular-weight hyaluronic acid or other derivant, the ability of adenovirus mediated transgene expression of their inhibition or adenovirus infection.Carry out this screening process normally by with this sample and known for adenovirus mediated transgene expression or infect effective composition and make comparisons, the known valid compositions will provide in this description and embodiment.
